I have examined the type material of P. concolor Womersley and of Bagnall's two species P. carpenteri and P. womersleyi. I am satisfied that all three are the same species for which the name P. concolor Womersly must take priority.
The main variation of this species lies in the number of vesicles in the PAO which can range from as low as 20 to as high as 80. This variation can be traced through the material which was available to me both from the British Museum and from my own collecting in Britain.
P. concolor is generally white, to creamy-white or greyish white in colour. It varies in length from 0.8 mm to 1.2 mm. The clothing is moderate of simple setae generally longer around Abd VI, with a tendency for a transverse row of short setae to occur around the posterior margins and a similar band of slightly longer setae around the anterior margins of each segment. Ant IV (Fig. 19) with up to four curved sense rods, a very small superficial sense rod in a pit, and clothed with short simple setae.
The sense organ of Ant III consists of a pair of very large rectangular to kidney-shaped sense clubs on short rod-like bases, situated behind a low tuberculate cuticular fold with a short central guard seta, three longer lateral guard setae and a single short straight exposed sense club to one side (Figs. 20, 22, 27). The PAO with 18-80 contiguous vesicles primarily lying at right angles to the long axis of the organ, and appearing superficially as in Fig. 18. Under closer examination the PAO shows prominent basal lobes of attachment as in Fig. 16.
Mandible with three strong apical teeth and well developed relatively small molar area (Fig. 26). Maxilla head with three apical teeth and three toothed lamellae (Fig. 23). Pseudocelli very small and obscure appearing as in Fig. 17. Abd VI and the margins of the other abdominal segments with a tendency to coarser tuberculation of the cuticle than the remainder of the body. Abd VI bears two large, curved anal spines on papillae, touching at their bases. Two chitinous tuberculate ridges occur on each side of the anterior margin of Abd VI; these are probably what Bagnall called "tooth-like projections near base". The posterior of these each carries a long simple seta on the outer edge (Figs. 25, 28).
Foot with simple untoothed claw having a fairly long basal seta to each side. Unguiculus vestigial and spine-like (Figs. 21, 24).page 7
